IPC: H02P6/182
Filed: 2017-08-22
Abstract: To provide a motor driving control device capable of avoiding resonance with the natural frequency of a motor produced within a predetermined rotating speed range and ensuring a desired rotating speed, while having an inexpensive configuration.SOLUTION: A motor driving control device 1 includes a motor driving unit that drives a motor by applying voltage to each phase of the motor, a rotation-position detecting circuit 5 that generates rotation position information, and a control unit 4 that outputs, to the motor driving unit, a driving control signal S4 for controlling driving of the motor driving unit. When the actual rotating speed of the motor 20 as the driving control signal S4 is equal to or higher than a predetermined rotating speed which is lower than a target rotating speed, the control unit 4 outputs a first driving control signal to control energization-switching-time adjustment for reducing resonance between the natural frequency of the motor 20 and the rotation component of the motor 20. Also, when the actual rotating speed is lower than the predetermined rotating speed with respect to the target rotating speed and the setting duty is within a maximum value error range, the control unit 4 outputs a second driving control signal to control normal energization switching without performing the energization-switching-time adjustment.SELECTED DRAWING: Figure 1
